Eh, they're just words. I agree that using them too much "dilutes" them, but is that really anything to do with them being swearwords? Or because they're the same word I used 20 times in a two minute conversation? Literally, when I literally use the same word in literally every other sentence, you'll literally start to doubt that I even know what the word "literally" literally means.

Personally, I think that most swearwords are pretty versatile. Especially fuck. Fuck can be serious. Fuck can be fun. Fuck can be casual or intense. Fuck isn't a monolith, it's all in the context, tone, and delivery.
